Equalizer

This device has a parametric digital equalizer. In this case, parametric means that in each of the five filters, one individual frequency can be em- phasised or reduced (with a gain of +8 to -8).

The following filters are available:

●	SUB LOW EQ	32	- 50 Hz
●	LOW EQ	63	- 250 Hz
●	MID EQ	315 - 1,250 Hz
●	MID/HIGH EQ	1,600 -		6,300 Hz
●	HIGH EQ	8,000 -		12,500 Hz

These filters can be set without using any measuring instruments. You can use them to make a significant differ- ence to the quality of the sound in the vehicle.

Adjustment Instructions

We recommend that you use a cassette with which you are familiar, or a CD if a CD changer is connected, for the pur- poses of this adjustment.

Zero the tone settings and deactivate the loudness before making any adjust- ments to the equalizer. Read the sec- tion on “Tone and volume” for more information about this.

➮Listen to the cassette or CD.

➮Compare the sound you hear with how you feel it should be.

➮Now consult the “Equalizer Adjust- ment Guide” table for “Tone Impres- sion”.
